NEA Air Classifier

Product Brochure (PDF 1738k)

The NEA series of air classifiers have been developed specifically for ultra-fine products with high added value. These high performance classifiers are ideal for the production of toner and other similar products due to their high separation sharpness.

Design:
  • Ecutec's NEA turbo air classifiers produce fine powders by separating a defined grain size from a fed turbulent air flow by creating a “virtual” mesh with a fast rotating classifier wheel. The suction force of the air stream normally produced by a ventilator forces the fine particles though the classifier wheel into a filter where the particles are separated from the air stream. The coarse particles fall down and are washed out again through new incoming air and feed material.
  • The direct drive of the classifier wheel guarantees the highest possible tip speeds allowing the NEA to produce very fine products.
Applications and Processes:
  • Suitable for a variety of dry powders especially for high-added value products like abrasives, metals, toners and pharmaceuticals.
  • Solid ceramic rotors available in alumina, silicone carbide and silicone nitrate make the NEA perfect for abrasives and non-ferrous production.
  • Ideal for pharmaceutical batch processes.
Features and Benefits:
  • Cut-points starting from d98 < 2μm up to 50μm and from lab-size to 24 t/h feed
  • Housing lined with ceramic or polyurethane
  • Stainless steel construction available
  • Innovative axial blades for improved recovery
  • Direct Transmission
  • Minimal maintenance due to robust design
  • Low specific energy consumption
